`PurePath.__init__()` incorrectly uses the `_raw_paths` of a given

This change makes the `_raw_paths`-enabled deferred joining apply _only_
when the path flavours match.

In some locales (like French or Hebrew) the full or abbreviated names of
the default month and weekday used in __calc_date_time can be part of

correctly distinguish formats %a, %A, %b, %B and %m.
Cycle all month and all days of the week to find the variable part
and distinguish %a from %A and %b from %B or %m.
Fixed locales for the following languges:
